bDefinite/b integrals have blimits/b, which are written above and below the integral sign.

Definite integrals usually produce a bvalue/b.

(\displaystyle\boxed{\int_a^b{f'(x)} dx = \Bigf(x)\Big_a^b = f(b) - f(a)} )

Due to the subtraction, there is no constant of integration.

Tip: Definite integrals can be done on a calculator using the (\boxed{\textstyle\int_{\square^{\square{\square}})}} button. You still need to do the algebraic working to get the marks, but you can check your answer on a calculator.
